t Beitknownthat-I, 'JAMES ELLWooD JONES, a citizen oflthelUnited States of America, residing at Switchback, inthe county of Mc# Dowell, in the State of WestVirginia, have invented certain new and useful Improvements in Machines for Discharging CokeOvens, of p whichthe following is a specification.

` This `invention relates to a coke-puller del 4 lo signed to be operated by machine for pulling.

coke from coke-ovens, and it adapted for discharging coke cokeovens.

lurgical coke is particularly from beehive In the `manufacture of metal.- the oven known as` the bee-t' l5 hive oven, so called because of itsdome# shaped form,

has been generally adopted, be-` ing found to give thehbestresults. In the *burning of the coke the coke is -produced in l 3, acaked mass p l 1 t :o and' it is desirable to avoid as much as possi- A having a verticalstratication blebreakage of the sticks and lumps extracted from the oven. p l t `The invention-relates more especially to aV "coke-puller having an uuderworking orwedge z5 `shaliedscraper operating on the instroke intop-` `the oven to loosen thecoke for withdrawal` and p rovided with adjustableA means opera, tiveon the outstroke for grasping or holding loosened coke disposed over and above the"l oven maybe obtained.f

l `The object offth'e invention is to provide 1 simple and effective means for operating and,`

controlling Athe grasping or holding device,

`35` which is utilized on the outstroke for removing the-mass of coke loosened on the instroke. Figure loftheaccompanying drawings representsa side elevation, partly in section, of one embodiment of this mechanical cokeco ke'oven, a coke- `carforreceiving the coke pulled from the `oven, and a machine-car on which the puller is mounted, the oven and cars being in section and parts being brokenout.

Fig. 9 represents a transverse section on line 9 9 of Fig. 8 of the front end of thebar for operating the scraper and the auxiliarybar inclosed therein to protect it from the coke within the oven.

i' The same reference characters indicate the same parts inail of the gures.

Thiscoke-pulling apparatus may -be used for discharging various forms of coke-ovens.

The drawings represent fragments of a beehive coke-oven 10, provided, as usual, with `a top opening,

which serves for a feed and blast opening, and with a lateral dischargeopening 12. These openings are closed and sealed in the usual manner during the coking operation or a part thereof. A number of such coke-ovens are arranged side by side,

"and a railway-track is disposed in front which travel the coke-cars for receiving and conveyingaway the coke drawn thereof, on

from the oven. Any suitable means maybe employed fordisposing of the coke withdrawn A track 40 is disposed outparallel therewith, and a which theu discharging apside the track 20 machine-car 50, on

`paratus is mounted, travels on said track'40.

A suitable frame for supporting the mechanism of the coke-puller proper is 'mounted on the car 50. The platform of the machinecar is provided with standards, as 60, on one sideand with standards, as 62, on the other side thereof. The standards are connected by a longitudinal rail 64 and elongated anti- 65,66, and 67,`dis posed parother .in a horizontal4 plane about midway of the height of the main frame, and these rails and rollers form a guideway for the coke-puller, as hereinafter described.` 'Corresponding rails and rollers auxiliary bar and permitting it to be retractl TOO att-ached to the guide 127.

64 65' and 66 and 67' connect the standards at the other side of the car and form a guide for said coke-puller.

A horizontal driving-shaft is supported in bearings of the frame. This shaft is provided wit-h a driving-crank 71 and a ily-wheel 72. Any suitable engine may be employed for imparting motion to the driving-shaft. 'lhis engine may be provided with any means usually employed for stopping, starting, and reversing.

A vertical shaft 100 is supported at its upper end in a cross-bar 0f the frame and turns near its lower end in a bearing 56, fixedv to the platform of the car. This shaftis shown as broken off below said platform; but it may be connected by suitable clutch-gearing with one of the car-axles and utilized to drive the car along the track. The shaft-bearing 56 is provided with a shoulder' 57, which serves as a stop-bearing. A beveled pinion 90 is disposed ou and adapted to rotate with the driving-shaft. A beveled gear-wheel 101 is xed on the upper end ofthe vertical shaft 100 and meshes with the bevel-pinion 90 on the driving-shaft 70. This vertical shaft is provided with two loose beveled pinions 102 and 103, disposed one above the other in reverse relation to each other, the sleeves or hubs thereof being provided with clutch-faces. A sliding clutch 104 is splined to the vertical shaft between said pinions and adapted to lock the said pinions respectivelyl tothe shaft. A clutch-lever10bI actuates the clutch 104 and shifts into engagement with either pinion for driving the shaft 100 in eitherl direction. This clutch-lever is pivoted on an arm 107, The outer end of the arm is provided with three'locking-recesses a b c, and the lever is provided with a latch 108, adapted to engage said recesses. When the latch is in recess a, the clutch 104 is held in gear with the pinion 103, as shown in Fig. 2. When in recess c, said clutch is held in engagement with the pinion 102, and when in the notch b the clutch is disengaged from both pinions.

A swiveling carriage is mounted on the machine-car for carrying the coke-puller, which is thrust into and retracted from the oven' in pulling the coke therefrom. This swiveling carriage may be of any suitable construction. As herein shown, it comprises a rotarycircular base 110,disposed on the stepbearing 57 around the shaft 100, and a standard 120, mounted on said base. The rotary base is provided with a toothed ilange 111, forming a worin-wheel. A shaft 112 has a worm 113, engaging said worm-wheel, and a crank-wheel 114, whereby the operator may turn thecarriageasdesired. Thestandard120 is provided at its upper end witha horizontal arm 121, provided with an eye 122, through which the shaft 100 passes. This standard is also provided 4with ahorizontal shaft-bearing 123 and with two arms 124 and 125.

These arms are provided with horizontal guideways 126 and 127, disposed in alinement and serving to support the main actuatingbar of the coke-puller, as hereinafter described. A stub-shaft 130, disposed in the bearing 123, is provided with a beveled wheel 131, which meshes with both the bevel-pinions 102 and 103 and with a pinion 132.

A coke-puller proper comprising a scraper adapted for loosening a portion of the caked coke on the instroke and having an adjustable coke grasper or holder for grasping or holding the loosened coke over and above the scraper on the outstroke is mounted on and actuated from the swiveling carriage. This coke-puller may be constructed in any suitable form which adapts it for performing this double function. In the form of embodiment shown in the drawings it comprises a scraperbar 140, a beveled scraper 150 at the outer end thereof, an adjustable coke-grasper in the form of a swinging plate 160, a grasperbar 170, a flexible connection-180 between the grasper-bar and the swinging plate, and means for actuating said bars. The body of the scraper 150, which may be solid or of skeleton construction, is in the form of an edge attached to-the bar 140 and beveled downward from its rear face 153 to its thin front edge 151. The front edge is preferably arc-shaped to conform to the curvature of the oven-wall, and the rear face is preferably straight and at an abrupt angle to the inclined upper face. This bod is preferably provided on its under side with antifrictionrolls 154 and 155, which travel on the ovenbottom. The scraper-bar is supported in the guideways 126 and 127 of the swiveling carriage and also in the elongated sta- ICO tionary gudeways at opposite sides of the y machine-car, which latter permit the bar to swing horizontally to different angles as the supporting-carriage swivels. The inner portion of this bar is provided with rack-teeth 141, which engage the pinion 132, whereby said bar is reciprocated tothrust and retract the scraper. what enlarged and hollow alongits front portion and provided therein with guides 142 and 143, and along its rear portion it is provided with a longitudinal channel or slot 144 and near its outer end with a notch or stop 145.

The coke-grasper is shown in this instance in' the form of a swinging plate 160, hinged to the upper angle of the scraper and extending in a transverse direction to the bar This bar is preferably some- TIO IIS

140. This plate has a beveled outer edge 161,

short rear portion 173, which rests on the bar 140. The eXible connection between the coke-grasper and its actuating-bar isslown in this instance fin the form of an elongated y link 180, pivoted at ating the grasper-bar 170 to raise or lower the grasper 160. The means shown for this purpose comprises a lever 190, pivoted to an arm 129, attached to the guideway 127 of the carriage and carrying at its outer end an automatic clamp.` This clamp is shown as'consisting of.` a box 19l,\through which the bar i 170 is passed, said box being provided with `upwardly-prol'iecting lugs 192 and 193 and with a slot 194 in its upper side. An eccentric 195 is pivoted at 196 to said lugs and falls through the slot 194, restingfnormally in front of its eccentric per face of the bar 170, whereby it is adapted to operate as a clamp to bite and hold said "barwhen the box ismoved frward.` This r clamp is provided with an automatic means forreleasing the bar 170 when it has made a sufficient thrust to place the coke-grasper in operative position, whereby any danger of breakage ofzthe parts is avoided. To this endthe clamp-disk is'providedwith a` stud 197, and an arm`198 is attached to the guide `way 127 or otherpart of the carriage adjacent tothe lever 190and carries an inclined face "199, andwhen the forward thrust of the clamp active. This lever is provided with a usual` i and a spring 205 for positively actuat'ingsaid lpawl.

one end to said release-rod and at the other Vend to the bar 140, tends to hold said releaserod out of contact with the pawl. This release-rod is provided with ratchet-teeth 222, and a lever 230, pivoted to a bracket 231, attached to the guideway 127, is provided with a pawl 232, which engages the ratchet-teeth of the release-rod'. The arm or bracket is provided with a stop 233 for said lever, and a spring 234, connected at one endwithksaid lever and at the other end to said arm, tends to hold the lever in retracted position.. The ratchet-teeth extend' along the release-bar a suliicient distance to enable the bar to be readily grasped by the actuating-lever in the `different positions of the coke-puller. The arm 231 is provided with a stop 238, which holds the pawl 232 out of contact with the ratchet-teeth when the lever is in its normal position. A stop'237 at the inner end of the lever 230 limits the swing of thepawl. A spring 235 tends to press the pawl toward the release-rod.

`In the use of this coke-drawingapparatus when the oven is ready to be discharged the machine-car 50 and the receiving-car 30 are moved into position opposite the lateral ovenopening 12, the closure of whichis removed, the engine is started and the driving-shaft moves in the direction of thearrow 73 in The operator then by the lever106 shiftsthe clutch 104 into engagement: with the pinion 102 on the vertical shaft 100. The coke-puller is thereby thrust into theoven, and the scraper thereof moves over the bottom of the oven a sufficient distance tomake .a proper drawing of the coke.

On this instroke of the coke-puller the Aplate 160, constituting the beveled face of the scraper, is in lowered or closed position and operates as a wedge to lift the coke above it from the caked Vmass of coke within the oven. lAt the end of the instroke the lever 106 is shifted so .as to disconnect the pinion 102 from the shaft 100, and the inward movement of the coke-puller is stopped. Then the lever 190 is moved toward the right, and the clamp 195 engages the bar 170 and imparts thereto an inward thrust suliicient to raise the plate 160 into active po- Ifo sition, as indicated in dotted lines in Fig. l,

and the pawl 200 engages the notch 145 `and holds said plate in raised position. This upward swing of the plate 160 lifts the mass of cokeimmediately above said plate and thrusts it behind said plate and places the plate in position to engage the depth of loosened coke above the body of the scraper on the outward stroke. The operator then shifts the lever 106 and brings the clutch 104 into engagement with the pinion 103, whereby the actuating-bar is retracted and the coke-puller t withdrawnfrom the oven with its plate in raised position, and substantially the whole mass of coke which was loosened on the instrokeis discharged into the coke-car 30. Then the leverl106 is shifted to disconnect the clutch 104 from the gear 103, wherebythe retraction of the coke puller is stopped. Then the lever 230 is made to operate the release-bar 220 and the locking-pawl 200 is lifted out of the notch 145 on the bar 140 and the bar 170 is pulled back by its spring 210, closing the plate 160, ready for another stroke. The first few strokes of the coke-puller are preferably in a direct line at right angles to the tracks, two or more drawings being usually required to remove the coke throughout a diameter of the coke-oven. After this is done lateral thrusts of the coke-puller are underworking wedge-like scraper movable over the bottom of a coke-oven and adapted on its instroke to loosen coke for withdrawal, a swinging plate hinged thereto and constituting the front thereof, and means connected with the under side of said plate for adjusting it in holding position on the outstroke.
